SPECIFICATION forming part Of Letters Patent No. 348,729, datedSeptember '7, 1886.

Application filed February 5, 1886. Serial "Na 190,890. (No model.)

To all whom it may concern.-

Be it known that I, HIRAM G. FARR, of Boston, in the county of Suffolkand State of Massachusetts, have invented certain Improvements inLubricating Bearings for the J ournals of Car-Axles, 850., of which thefollowing is a full, clear,.and exact description, reference being hadto the accompanying drawings, making part of this specification, inwhich Figure l is a perspective view of my improved bearing inverted.Fig. 2 is a longitudinalsection through the center of the same appliedto the journal of a car-axle; Fig. 3, a transverse section on the line00 m of Fig. 2; Fig. 4, a perspective view of a block of felt which ispreferably employed under the axle in connection with my aforesaidbearing, said block of felt, however, forming the subject of anotherapplication for patent filed simulta neously herewith; Fig. 5, atransverse section showing the application of my invention to theordinary bearing for shafting. Fig. 6 shows the application of myinvention to the hub of a loose pulley; Fig. 7, a transverse section ofFig. 6.

The aim of my present invention is the reduction of the friction andconsequent wear of the journals of car-axles, shafting of machincry,loose pulleys, &c., and the surfaces of the bearings or parts with whichthey come into contact; and this invention has for its prominent featurea bearing located above the journal and provided with one or moregrooves or channels, in combination with and for the reception of one ormore strips of felt or other similar absorbent material supplied with alubricant, this feature of my invention being preferably, but notnecessarily, associated with a block or strip of similar absorbentmaterial located under an axle rotating in an axle-box having anoil-reservoir, a similar strip of absorbent material being also appliedto the bearing of ordinary machine-shafting, and being preferablylocated within a groove in'thev upper part of the bearing, wit-h anoil-passage communicating therewith.

In the said drawings, A represents a metal bearing,providedwith atransverse groove, a, located at the center of its under side, for thereception of an annular shoulder or projection, b, formed on the journalB of a car-axle, O, at

a point about one-half the 'distancebetween other two annular shouldersor projections, c d, thereof. Longitudinally within the hearing A, andextending from its under side to a depth equal to about one-half of itsthickness, are formed two parallel grooves, e e, situated equidistantfrom a vertical plane passing through the axis of the journal. \Vithinthe grooves e e are located strips h h, of any suitable absorbentmaterial-for instance, felt or other textile fabric of similarcapacity-for taking up the lubricant 1', located in the axle-box, whichlubricant, when reaching up to or above the bottom of the journal, iscarried up by its rotation and fed to the strips h h, which thus becomesaturated with and transmit the desired quantity of the lubricant to thelower surface of the bearing A in contact therewith, whereby the wear ofthe journal and the under side of the hearing A is reduced to a minimumand the speed desired is obtained with the least expenditure of power.\Vhere the journal is not provided with a central or intermediateannular projection, the groove 6 in the bearing is omitted, the latterbeing prevented from any lateral movement independently of the journalby its two other annular shoulders, c (1, while the bearing is kept fromany vertical movement independently of the axle-box by means of a plateor key, D, interposed be tween them. (Figs. 2 and 3.) The efficiency ofthis feature of my invention (to wit, the bearing) is enhanced by theemployment of a block of felt, G, (one form of which is shown in Fig.4,) located under and incontact with the rotating journal, said blockGbeing cutaway in such manner at its ends and center to adapt "it to fitthe annular projections b c d of the application for patent madesimultaneously and bearing even date herewith.

In its application to the bearing of ordinary machine-shafting theunderside of the upper I claimportion of the bearing H in contact withthe A hearing, A, having in its under sidea pair I5 upper portion of theshaft is provided with a of longitudinal grooves, 0 e, and a transverseSingle groove, Z, cut transversely with the groove, a, locatedintermediate of its ends, in

5 bearing for the reception of a single strip, m, combination with andfor the reception of of felt, (see Fig. 5,) and an oil-passage, n, leadsstrips, hi1, offelt, 820., and ajournal, B, having from the top of thebearing down thereto. an annular shoulder, b, as and for the purpose 20To apply thisinvention to a loose pulley, L, specified. g j i I it issimply necessary to form agroove, 1;,with- Signed this 2d dayofFcbruary, 1886. r 10 in the hub for the reception of a strip, 1, offelt, HIRAM G.
